I said no. Was going to make less than 1% difference to my 10 year outcome. I did a lot of reading. Tamoxifen doesn’t prevent cancer, doesn’t cure cancer, can cause cancer, permanently alter cell DNA, can slow the growth of cancer that feeds off estrogen. There was a study looking at the benefits of giving it to women without BC too see how that effected the likelihood of them getting BC later. Interestingly the study was disbanded and no report released.
I was 42, a fair way off natural menopause. I wanted quality of life, for as few or many years as that may be. To look after the body parts that need estrogen to function. Keep my eyes, brain, bones, etc working as well as possible.
Chemo oncologist said, “you probably don’t have cancer anymore “. Yet he was willing to give me chemo, again for less than 1% possible benefit to my 10 year outcome. I am astonished that something so toxic can be recommended to people in a vulnerable situation for so little or no possible benefit.
There is also interesting research regarding alzheimer's and there’s thinking that the reason more women are affected than men is due to the dramatic drop in estrogen after menopause. Given my grandma ended up with alzheimer's I’m keen to defer that as long as possible. Definitely don’t want symptoms in my 50s.
There are no guarantees with cancer treatment. Balance what you need to do based on your priorities. There might be a trade off between peace of mind, quality of life, quantity of life.
All the the best to everyone with their treatment decisions. Xx
